Hi to all
I made my first 18650 battery pack a few month ago and since then I have made a few others for some family members and friend because I love to do so, I always enjoy all the online debates about the capacity and the range, PAS or not, how many miles per charge and all that. Everybody seems to have different opinions and specific results. I'm trying to find a way to test the packs right after I build them under different loads and that way kinda have an estimate on how is going to behave in real live, (Voltage sag, current drawn and working temp). this is the tricky part. I want to test 12-72V packs (84v if fully charged) and 0-35A, about (1500 -1800 Watts max). This is my idea:
Testing parameters:
12v packs - 250-350 Watts (20-30AH)
24V packs - 250-500 Watts (10.5-21AH)
36V packs - 250-750 Watts (7-21AH)
48V packs - 250-1200 Watts (5-25AH)
60V packs - 250-1500 watts (4-25AH)
72V packs - 250-1800 Watts (3.5-25AH)
testing lab
1- Battery Pack (12-84V) (10.5-35AH) connected to:
2- Meter (V,A,Watts) (12-84V) 35A connected to:
3- dc/dc converter - (12-84V) to 24V connected to: (the main problem is that this dc/dc converter has to be rated 90-100A)
4- Pure sine wave inverter 24V dc to 110 AC 2000 Watts connected to:
5- House appliances 110V (250-1800 Watts)
If anyone have a better idea (something simpler or cheaper) or have done anything similar and can point me on the right directions (what to buy and where) Thanks in advance for taking your time to help me
